Milestone 2: Matured Version (MLP)

Expanding institutional connectivity, hardening test coverage across all drivers, and delivering user-facing documentation for production readiness.

Production Institutional Signing Drivers: Delivery and integration of production-ready signing drivers for major institutional wallet providers, fully leveraging the driver framework established in Milestone 1.

Acceptance:* E2E integration logs demonstrating successful transaction signing via at least one distinct institutional infrastructure provider. This validates the multi-vendor scalability of the Gateway and secures out-of-the-box compatibility for institutions.

Multi-Session Support: Implementation of concurrent user handling.

Acceptance:* Automated test execution proving a single Gateway instance can concurrently handle two distinct user sessions without state bleed.

UI/UX & Canton Ecosystem Branding: Update of the Gateway interface to adhere to Canton Foundation guidelines.

Acceptance:* Visual review and sign-off by a Foundation designated UI/UX representative.

User Documentation: Delivery of comprehensive end-user materials.

Acceptance:* Publication of a UI user manual.

External Security Audit: Delivery of a finalized security audit report from an independent, reputable Web3 security firm covering the core Gateway architecture and CIP-0103 implementation.

Requirement:* All findings classified as "Critical" or "High" must have a verifiable patch merged into the main branch.

Code Quality: CI/CD pipelines must report maintaining:

At least 80% Unit Test coverage. At least 80% E2E test coverage that explicitly includes all institutional driver flows.
